Smoker&#39;s pipe



May 27, 1947- D. P. LAVIETES' SMOKER S P IPE Filed June 13, 1944 A 147TOR/V5 Y Patented May 27, 1947 UNIT STATE OFFICE The invention relatesto smokers pipes and more particularly to a pipe having a briar woodbowl and a push bit.

In the production of wood blocks from briar roots, the contour of theseblocks from which stummels are made upon a irazing machine, has widevariation accordin to the number and size of blocks which can be cutfrom the same or from different roots. Because of irregularity in thesize and shape of such roots, the operator of a cutting saw mustexercise his judgment in order to produce as great a number of usableblocks from each root as is possible though such block may be suitablefor different styles, sizes and shapes of pipe bowls. As a result blocksof many difierent sizes and shapes are cut from the same root andbecause of the necessity of having blocks of a size and shape to includein the stummel wood in sufficient quantity to provide not only the bowlproper but an integral stem, the percentage of wastage of material whencutting the blocks has been fairly high.

In smokers pipes, the integral stem lacks sufficient bulk to aiiord asuitable support for the removable bit and it has long been thepractice, whether a screw or a push bit was used, to reinforce the endof the stem either by a metal band or a, metal fitting engageable by thebit, so that likelihood of splitting the stem and possibly the bowl fromexcessive stresses due to expansion of the wood of the stem frommoisture drawn from the bowl with the smoke, or the tendency of a pipesmoker to exert excessive strength in applying the bit in an effort tosecure a tight joint between the stem and the bit, is minimized.

Much of the wastage in cutting briar roots is in the form of blockshaving dimensions which do not admit of their use in forming a stummelhaving an integral stem of sufiicient length to permit the usualpractices to be followed in applying a bit thereto or provide adequategripping area to enable the use of a reinforcing band or a metal fittingto resist crackin of the material and facilitate the application of abit to the-bowl.

Prior to my invention, such small or oddly shaped blocks werecustomarily disposed of by using them as fuel in the furnace of thesteam plant of a factory producing such blocks, and except for this usewere a complete loss. They had no marketable value to pipemanufacturers.

To avoid such wastage of briar wood, I have produced a pipe having abowl formed of such wood but lacking an integral stem so that the bit isapplied directly to the bowl in a manner not only to ensure a tight,non-seeping, joint, but to secure such a joint without excessivepressure upon the bit. The construction of the pipe is uch as to providesufiicient bulk of the hard wood of the bowl where it is engaged by thebit, to prevent possible cracking of the wood either from pressuredeveloped when applying the bit or from. expansion of the wood whenpartially saturated with pitch, tar and other liquids accumulated in thebowl as a result of usage of the pipe.

The bit itself is made of material possessing some resiliency and whenmade of wood which is preferable, is of softer and more porous materialthan the briar wood of the bowl, and by reason of its bore, may havesome degree of expansion without developing crackin stresses upon thebowl.

The socket communicating with the bowl and serving as a means ofattachment of the bit, and one end portion of the push bit are so formedas to limit the expansion pressures which may be developed when applyinthe bit and yet ensure a tight fit with movement of the bit inwardly ofthe socket even to a variable extent.

By utilizing what would otherwise be waste blocks of briar root in theproduction of pipes embodying the invention, I am enabled to producepipes at a cost approximating that of the labor required in finishingthe pipe, and the cost of the material of the bits, without sacrificingthe quality of the finish, or the durability of the plpe.

The invention consists primarily in a smokers pipe embodying therein abriar wood bowl having a socket within the material of the Wall of, andcommunicating with the bore of the bowl and opening outwardly of saidbowl, and a bit one end of which has a heady which conforms to and hasa. close friction fit within said socket whereby crackin of the briarwood of the bowl from expansion thereof or cracking of the material ofthe bit due to excess pressure when applying the bit to a bowl, isprevented, and in such other features of construction as are hereinafterdescribed and more particularly pointed out in the claims heretoappended.

Referring to the drawings,

' Fig. 1 is a side view of a smokers pipe embodying the invention withthe lower part of the bowl broken away, and

Fig. 2 is a similar view with the bit positioned for application to thebowl, the end of the bit engageable with the bowl being broken away.

Like numerals refer to like parts in both of said views.

In the embodiment of the invention shown in the drawings, the bowl it isformed from a block ofbriar woodhaving the general form of aquadrangularprism, although a slight protuberance may be formed duringfrazing where the stem is to be applied thereto.

The bowl it] has the usual bore I! and within the wall of the bowl is asocket l2 one end of which communicates with a portion of the bore H adjacent the bottom thereof and the other and larger end of which opensoutwardly of the bowl. This socket has a cylindrical taper or is intruncated conical form with its largest diameter as 5 stated openingoutwardly of the wall of the bowl. When as shown in the drawings, aprotuberance as I3 is present, this materially increases the thicknessof the wall of the bowl about said socket so as to permit a socket ofconsiderable depth to be formed. and yet afford sufiicient bulk ofmaterial to resist cracking stresses from the bit. With this form ofbowl, communication of the socket with the bore H may be through a shortand small smoke opening Hi adjacent the bottom of the bore H.

Adapted to be attached to the bowl H! by means of the socket i2 is apush bit having at one end thereof a tapered cylindrical or truncatedconical head it the outside graduated dimensions of which correspondwith some portion of the graduated inside dimensions or the socket l2 soas to have a close friction fit within some part of said socket 12.

This construction permits the head of the bit-5. 7

to adapt itself to some part or said socket by a variable lengthwisemovement of the bit until a tight joint is secured without thedevelopment of excessive pressure upon the bit. The length or depth ofthe socket i2 is greater than the length;

of the head 65 and the greatest diameter of the head is less than thegreatest diameter of the socket so as to prevent said head fromprotruding beyond the outer wall of the bowl. The inner end of thesocket is slightly smaller in diameter;

than the minimum diameter of the head, and the outer end of the socketis slightly larger than the maximum diameter of the head.

The portion it of the bit adjacent the portion of the head having thegreatest diameter, is of;

making unnecessary the usual grinding operation in fitting a bit to abowl in the factory.

By the use of an inwardly tapered socket l2 and a bit having a similarlytapered head I5, as described, any slight variance in dimensions of thesocket or the head requires merely a difference in the endwise movementof the bit in order to secure a tight joint. With such a construction,no great nicety in the dimensions of the socket i2 and of the head 15 isrequired, since so long as the inner wall of the socket and the outersurface of said head have the same degree of angularity to the axis ofthe socket and the head, a tight fit of the bit is assured at some pointof engagement with the wall of the socket.

Furthermore, any slight change of dimensions of the socket or of thehead of the bit from heat or moisture, does not interfere with thefitting of the bit and the securing of a tight joint between the head i5and the bowl of the pipe upon replacing the bit in the socket I2.

No reinforcements for the bowl or in the bit are used or required andsince no metal fittings are used in connecting the bit with the bowl, atight fit is assured not only because of the form of the socket and ofthe head 25, but because a more effective joint is secured by a wood towood contact than with a metal to metal or a metal to Wood joint.

Bowls may vary widely in their general contour without affecting theresults above referred to, and diiferent materials such as wood, horn,rubber or plastic may be used-for the bits within the limitations hereinspecified. An essential characteristic of the invention, however, is adi rect connection of the bit with the bowl so as to utilize the bulk ofmaterial in the bowl to resist cracking of the bowl from stressesdeveloped in the use of the pipe or when applying a bit to the bowl.

Having described the invention, what I claim as new and desire to haveprotected by Letters Patent is:

1. A smokers pipe embodying therein a briar wood bowl having a bore anda tapered, truncated conical socket within the material of the wall ofsaid bowl, said socket having its end of largest diameter openingoutwardly of said bowl and the opposite end in communication with saidbore, and a bit having a tapered, truncated conical head, the outer faceof which has substantially the same degree of angularity as said socketand the greatest diameter of said head being less than the greatestdiameter of said socket whereby said bit will adapt itself to some partof said socket to form a tight friction joint therewith and cracking ofthe briar wood of said bowl from expansion thereof or of the material ofthe bit, or from excess pressure when applying the bit to a bowl, isprevented.

2. A smokers pipe embodying therein a wooden bowl having a bore and atapered, truncated conical socket within the material of the wall ofsaid bowl, said socket having its end of largest diameter openingoutwardly of said bowl and the opposite end in communication with saidbore, and a bit having a tapered, truncated conical head of a. lengthless than the depth of said socket, the greatest diameter of said headbein less than the greatest diameter of said socket, the outer face ofsaid head having substantially the same degree of angularity as saidsocket whereby said bit will adapt itself to some part of said socket toform a tight friction joint therewith and cracking of the wood of saidbowl from expansion thereof or of the material of the bit, or fromexcess pressure when applying the bit to a bowl, is prevented. 7
